VARIATIONAL PRINCIPLE FOR THE VELOCITIES OF PARTICLES OF A VISCOPLASTIC STRIP UNDER ROLLING
DOI: 10.17804/2410-9908.2019.1.064-069 Plane flow of a viscoplastic strip under rolling is considered. Tangential friction stresses at the flow–roll interface and at contact of the flow region with the rigid strip ends are specified approximately by the Prandtl friction law. A variational principle is proved for particle velocities with account of the convection flow.
